Paulina M: These are levis jeans. There are sustainable and they are a good quality product so they should last about a year. I don't personally buy their jeans but I think they are doing a great job by improving the way they make them.
And though your dreams may toss and turn you now They will vanish away like your dads best jeans Denim blue, faded up to the sky And though you want them to last forever You know they never will And the patches make the goodbye harder still.
